Field of the Invention The present invention relates to a method of manufacturing a carrier board, and more particularly to a method of manufacturing a board in which an element is embedded in the present invention. [Prior Art] The so-called "Embedded Passive" (Embedded Passives) uses the inner layer process of the multi-layer board to adopt the residual engraving or printing method to directly form the capacitor or resistor on the inner layer. After being laminated into a multi-layer board, it will replace the discrete passive components soldered during assembly on the board surface to save the board surface to the active components and their routers. Buried implantable or hidden technology '. The earliest is Ohmet-ply's use of the inner surface of the original copper foil on the matte surface (MattSide), in addition to the upper film of the nickel alloy layer, t into a resistive component (ResistiveElement) and press-compressed into Thinc〇re, and then use the technique of two photoresists and three times of remnant to form the desired film "resistor" at a specific position. Because it is buried in the inner layer, the trade name is called BuriedResist〇r (BR). After that, in 1992, Zycon, a PCB manufacturer in the United States, used a very thin (2_4 mil) inner layer of the dielectric layer in the high-order multilayer board outside the original Vcc/GND inner layer, using its large area. The parallel metal copper plate is made into a monolithic capacitor. The trade name is Buried Capacit〇r (BC). The advantage is that it avoids noise, provides charge energy, and regulates voltage at the fundamental frequency. Zycoii has also applied for several patents on 0〇 (ie US Patent Nos. 5,079,069, 5,161,086, 5,155,655). 200934333 At present, the shooting system has embedded the concept of buried passive components to embed electronic components such as active components to improve the listening density of the clock. In this Wei Qiancai, the holes are mainly dug in the insulating material, and then the electronic components are mounted in the pockets. However, in this practice, the portion of the insulating material is still present under the electronic component, which makes the overall thickness or density still not optimal. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a method for manufacturing a circuit board embedding a component of the present invention, which mainly records electronic components on the conductive test of Kellin, so that the lower elements of the electronic components are not insulated. Layers, while achieving the best density of buried electronic boards. Based on the above object, in the manufacturing method of the circuit board embedding the component of the present invention, the electronic component (10) (mounted on the electroless metal layer (I2) is mainly mounted on the carrier plate (10) of the electroscope metal layer (10). ' Then the metal layer (10) is pressed onto the plated metal layer (10) and the carrier plate (10) of the electronic component (10) by means of a dielectric film (18), and after removing the carrier plate (10) 'A patterning process is performed over the exposed layer of electro-mineral metal (10), and the metal layer (20) and/or the electromoney metal layer (10) are patterned into a wiring layer (24). The advantages and spirits of the present invention can be obtained by the following detailed description of the invention and the accompanying drawings. [Embodiment] 4A1 to 1HFig. 1A to 1H are diagrams of the method for manufacturing a circuit board of the invention. schematic diagram. As shown in Fig. 1A, first, a carrier plate (10)' on which an electroplated metal layer (10) 200934333 is plated is provided, and the material of the carrier plate is a conductive material, and the material of the electrically forged metal layer (12) is copper. Briefly, in the manufacturing method of the circuit board in which the component is embedded in the present invention, the electronic component (16) is mainly mounted on the carrier plate (10) on which the plated metal layer (12) is plated as shown in FIG. 1C. (Installed on the electroplated metal layer (12)), and then press-bonded the metal layer (2〇) to the electroplated component (16) by the dielectric film (18) as shown in the mth figure. The metal layer (12) is placed on the carrier plate (10) and after the carrier plate (1〇) is removed, a patterning process is performed on the exposed metal layer (12), and the metal layer is formed. 〇) and/or the electromineral metal layer (12) is patterned into a wiring layer (24) 'as shown in the 1H. In this way, there is no insulating layer under the electronic component (16), and only has a circuit layer for external signal transmission (24, thereby achieving an optimal density of the embedded electronic board. 需 Need special shame] The electronic component (16) can be a passive component or a passive component, and the passive component can be a capacitor, a resistor or an inductor. To strengthen the bonding force between the metal (12) and the carrier plate (10), the carrier plate (10) has a rough surface. /, physically speaking, as shown in the figure, for the purpose of positioning, the SMT alignment reference can be formed on the metallurgical metal layer (12) to call her coffee. Then, as shown in the redundancy diagram, the money is shown. The electronic component (10) is mounted on the metal layer (12). Next, the metal layer (2) is pressed by the dielectric film (18) to the plated metal layer on which the electronic component (10) has been mounted, as shown in Figs. 1D to m. )... above the carrier board (10). Then, the carrier plate (1 〇) is removed, and the plated metal layer 200934333 (12) is exposed as shown in Fig. 1G. However, before the carrier board (10) is removed, an opening (22) may be formed opposite the electronic component (16) as shown in the IF diagram, so that the through hole of the external signal transmission of the electronic component (16) can be fabricated in a subsequent process ( Not depicted). Finally, the metal layer (20) and/or the plated metal layer (12) are patterned into a wiring layer (24) as shown in Figure 1H. When the metal layer (20) is pressed onto the plated metal layer (12) and the carrier plate (10) on which the electronic component (16) has been mounted, 'except for the means as shown in Figs. 1D to 1E' Other means are available. Please refer to FIG. 2A to FIG. 2B, and FIG. 2A to FIG. 2B are another schematic diagrams of a method for manufacturing a circuit board in which a buried circuit board is embedded in the device. As shown in FIG. 2A, the electronic component (16) is added under the electronic component (16). The insulating layer (13) is used to enhance the electrical insulation effect, and then the pressing is completed as shown in Fig. 1E. As shown in Fig. 2B, the insulating layers (26a to 26b) are placed first around the electronic component (16) and then the bonding is completed as shown in Fig. 1E. The insulating layer (2, such as ~2) may be a layer of insulating material having an opening with an opening size relative to the electronic component (16). With the above detailed description of the preferred embodiments, it is desirable to more clearly describe the features and spirit of the present invention. On the contrary, the purpose is to hope that it can cover all kinds of changes and equal literary genres.
